In late November, events will be held at independent sellers around the country, with writers stepping in to help sell books. Dunham, author of “Not That Kind of Girl,” plans to spend Nov. 26 at Book Soup in Los Angeles.

In a statement issued Wednesday through the booksellers association, Dunham said that independent bookstores were a “cornerstone” of her identity.

Bookstores, she added, were “places for learning, community-building, and falling in love with strangers.”
